Detailed Description
Benzodiazepines are widely used in pregnant women; however, their safety on congenital malformations in a real-world setting is still uncertain.
We aimed to assess the association between benzodiazepine use in early pregnancy and the risk of congenital malformations.
We will conduct a retrospective nationwide cohort study using the Health Insurance Review and Assessment (HIRA) database of South Korea, which covers the entire South Korean population.
